Green-backed Heron
"Green-backed heron" is a collective term for certain herons. Small and compact among herons, these birds often feature green plumage – rare among the Ardeidae –, in particular on the back, wings and scapulars. They were formerly believed to make up a single species ''Butorides striata'', but are now treated as three largely allopatric species: * Striated heron, ''Butorides striata'' – Widespread throughout the Old World tropics and in South America (Note that the grammatical gender of the specific name has been corrected from ''striatus'') * Lava heron, ''Butorides sundevalli'' – Endemic to the Galápagos Islands off Ecuador * Green heron, ''Butorides virescens'' – Widespread from temperate North America south to Panama These herons are tool-using animals. They are regularly seen picking up objects to use as a fishing lure, attracting prey fish.Norris (1975), Boswall (1983), Walsh ''et al.'' (1985), Robinson (1994) Image:Striated Heron (But ...

Heron
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and ''Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Green Heron
The green heron (''Butorides virescens'') is a small heron of North and Central America. ''Butorides'' is from Middle English ''butor'' "bittern" and Ancient Greek ''-oides'', "resembling", and ''virescens'' is Latin for "greenish". It was long considered conspecific with its sister species the striated heron (''Butorides striata''), and together they were called "green-backed heron". Birds of the nominate subspecies (no matter which taxonomic arrangement is preferred) are extremely rare vagrants to western Europe—for example, a sighting in Pembrokeshire in 2018 was only the second recorded sighting in Wales; individuals from the Pacific coast of North America may similarly stray as far as Hawaii. Description The green heron is relatively small; adult body length is about . The neck is often pulled in tight against the body. Adults have a glossy, greenish-black cap, a greenish back and wings that are grey-black grading into green or blue, a chestnut neck with a white line d ...

Butorides
''Butorides'' is a genus of small herons. It contains three similar species, the green heron or green-backed heron, ''Butorides virescens'', the lava heron (''Butorides sundevalli''), and the striated heron, ''Butorides striatus''. A fossil species, ''Butorides validipes'', is known from the Early Pleistocene of Florida in the United States. ''Butorides'' is from Middle English ''Butor'' "bittern" and Ancient Greek ''-oides'', "resembling". Adults of both extant species are about long, and have a blue-black back and wings, a black cap and short yellow legs. Juveniles are browner above and streaked below, and have greenish-yellow legs. The species have different underpart colours, chestnut with a white line down the front in green heron, and white or grey in striated. Both breed in small wetlands on a platform of sticks often in shrubs or trees, sometimes on the ground. The female lays three to five eggs. Both parents incubate for about 20 days until hatching, and feed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Ornithology
The ''Journal of Ornithology'' (formerly ''Journal für Ornithologie'') is a scientific journal published by Springer Science+Business Media on behalf of the Deutsche Ornithologen-Gesellschaft. It was founded by Jean Cabanis in 1853, becoming the official journal of the Deutsche Ornithologen-Gesellschaft in 1854. The first issue was produced in January 1853 and Cabanis noted that although there were specialist journals in entomology and conchology that there was nothing to deal with ornithology in Germany. Among the first essays published in the journal, was an essay by Reichenbach on the concept of species. According to the ''Journal Citation Reports'', the journal has a 2012 impact factor of 1.632.

Prey Fish
Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, silversides, smelt such as capelin and goldband fusiliers. Forage fish compensate for their small size by forming schools. Some swim in synchronised grids with their mouths open so they can efficiently filter plankton. These schools can become immense shoals which move along coastlines and migrate across open oceans. The shoals are concentrated energy resources for the great marine predators. The predators are keenly focused on the shoals, acutely aware of their numbers and whereabouts, and make migrations themselves that ...

Fishing Lure
A fishing lure is a broad type of artificial angling baits that are replicas designed to mimic real prey animals and attract the attention of predatory fish, using appearances, flashy colors, bright reflections, movements, vibrations and/or loud noises to appeal to the fish's predation instinct and entice it into striking. As a terminal tackle, lures are attached to the end of a fishing line and most are equipped with one or more hooks that come in various styles. They are designed to fool carnivorous fish and elicit an aggressive strike, the force of which will alert the angler (fisherman) to yank the line to secure a hookset inside the fish mouth. However some hookless lures are also used merely to bait the fish nearer, so it can be hooked by another lure or be captured via other means such as netting, trapping, impaling with a spear or pole hook, snagging, shooting or even catching by hand. Most lures are commercially made, but some are hand-made by the angler (such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tool-using Animal
Tool use by non-humans is a phenomenon in which a non-human animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, combat, defence, communication, recreation or construction. Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. There is considerable discussion about the definition of what constitutes a tool and therefore which behaviours can be considered true examples of tool use. A wide range of animals, including mammals, birds, fish, cephalopods, and insects, are considered to use tools. Primates are well known for using tools for hunting or gathering food and water, cover for rain, and self-defence. Chimpanzees have often been the object of study in regard to their usage of tools, most famously by Jane Goodall, since these animals are frequently kept in captivity and are closely related to humans. Wild tool use in other primates, especially among apes and monkeys, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
